Unfortunately, I don't have the deck space for propagation exeggcute. Even if I did, I would probably fill it with some sort of more useful tech or consistency card. In a deck like this where discarding cards doesn't matter much, I prefer to have another resource/ resource obtaining card than something to throw away. I often don't need any ERs because I generally have electrodes out on the bench to get me cards to discard for the couple of energy, plus, I run a Cilan as well, so I generally don't have that problem.
